problem installing ZA Extreme on a Dell XPS 430 WinVista Prem x64 SP2

About a month ago my DSL modem went down, and at the sametime ZA showed an X on it and the anti virus was missing from the about window.I have since got a new modem/router which took a few days to set up. I thenstarted to install ZA 12.0.104.000 again and every time it does the same thingas noted above. gone to Tech chat and got the same steps each time or now theycan't figure it out. I have runMalwarebyte two times first found something deleted off computer, second foundnothing, and then delete all traces of this program off my computer. then ranMS malicious software removal tool andfound nothing. I have no other Anti Virus on my computer.

The steps tech gives me are unistall ZA from programs, runthe clean tool, go to safe mode and run %temp% and delete files, run prefetchand delete files, go through C: and look for any files that have zonealarm orcheckpoint and delete, go to regedit and delete anything to do with zonealarm, checkpoint, kaparsky, clear out recycle bin. restart and go to normal shut down start upprograms, shut down Window firewall and reboot. Tech sent me a zip file of theprogram current version and I install and get the same problem, done about 20times. I even tried run as administrator no dice. I even added a new user andistalled from there no dice.

Re: problem installing ZA Extreme and entering the licence Key.

thank you both for your advice, the wonderful world of windows. I had a sick feeling I would have to rebuild the OS I did that four months ago after a weird crash of sorts. I use the recover disk to repair the OS and ended up rebuilding everything. And I think by reloading a backup I had, it loaded files that I don't have the original program for but the file are there, I have deleted most folders but I think there are files I don't know about that may be lingering. I will try the restore point step if don't work, OH! well we start over again.
